True real-time audio/video conferencing hasn't arrived yet for most. The bandwidth requirements remain excessive and quality of video, in particular, is fairly low. If you ever done live chat with audio and a web camera, you've seen limitations.
Most online presentations which involve both audio and video generally use static images which change either rarely or slowly, such as charts, website images, topic outlines and so on. This can be extremely useful for teleseminars, of course, because it makes it easier to demonstrate certain points and provides a visual as well as an audio focus for participants.
The combination of audio and visual elements is particularly useful in training situations where one can reinforce other. Plus, you have advantage of reaching those who learn better through visual means, as well as those partial to audio.
For those of you doing eCommerce evolved conference call can be an incredible tool. Consider how much impact regular teleseminars about your area of expertise could have on future sales. You can provide buyers with instructional teleseminars. You can introduce new products. And in each instance you'll be generating recordings which you can either sell or make available on your sites, or use as added viral marketing tools.
With increasing sophistication and usability of tools for conference calling, possibilities are virtually unlimited and well within reach of every entrepreneur. You'll be hard pressed to find another tool that offers you impact and potential of conference call.
